British Business Bank Fuels Growth with £50M Investment in Soho Square Fund II

The British Business Bank (BBB) has announced a significant £50 million cornerstone commitment to Soho Square Partnership Capital Fund II. This new fund is designed as a lower mid-market vehicle, specifically targeting founder-owned businesses across the United Kingdom by offering a unique structured capital solution. In addition to the BBB's substantial investment, the announcement also confirmed the involvement of several undisclosed US institutional investors, whose identities and aggregate commitments remain private.

London-headquartered Soho Square Capital focuses its investments on businesses with an EBITDA of up to £15 million and a turnover of up to £200 million. Its distinctive approach combines senior secured debt instruments with minority equity positions, providing portfolio companies with crucial access to growth capital. This method is particularly attractive as it allows business owners to secure funding without the significant dilution of their stakes that is often a requirement with traditional private equity terms. A key strategic mandate for Fund II is its geographical focus, with at least 75% of its capital explicitly earmarked for deployment within the UK, and a strong emphasis on supporting businesses located outside London and the South East, spreading investment across various nations and regions.

This initiative directly addresses a well-recognized "structured capital gap" in the UK's financing landscape. For established and profitable businesses seeking capital for a range of strategic activities – including acquisitions, management buy-outs, succession planning, or technology investments – the historical options have been limited. Founders typically faced a binary choice: either adhere to the rigid covenants and limited flexibility offered by mainstream bank lending, or accept the dilutive ownership structures imposed by traditional private equity firms. Neither of these routes is universally suitable, especially for founders committed to remaining actively involved in their businesses long-term. Structured or partnership capital, which strategically layers debt with minority equity upside, has emerged as a crucial bridge, attracting increasing institutional interest in the UK by offering a more flexible and less dilutive financing alternative.

Fund II's investment strategy is further aligned with national economic priorities, prioritizing sectors that resonate with the UK government’s Industrial Strategy. There is a specific preference for businesses operating within the digital and technology sectors, as well as professional and business services. The British Business Bank’s cornerstone commitment serves a dual purpose: it not only provides a foundational investment but is also explicitly intended to instill confidence in co-investors, thereby triggering the mobilization of further institutional capital into the vehicle. Adam Kelly, managing director and co-head of funds at the British Business Bank, underscored this, stating that the commitment "directly address[es] a gap in the debt market" and will unlock flexible capital for businesses "currently underserved by other lenders."

The British Business Bank’s involvement is a direct reflection of its five-year Strategic Plan, which strategically allocates capital for deployment across eight identified Industrial Strategy priority sectors. As a cornerstone investor, the Bank will also possess the right to participate in co-investments alongside the fund. This structural feature allows the BBB to gain potential upside exposure to the performance of the portfolio companies without assuming a formal general partner role. Blair McDougall, Minister for Small Business and Economic Transformation, situated this commitment within the broader framework of the government’s Modern Industrial Strategy, highlighting the critical role of access to capital for high-growth SMEs as a powerful lever for job creation and driving regional economic development.

Within the UK’s lower mid-market, the competitive environment for this type of funding is also evolving. In recent years, several private credit managers and specialist structured capital firms have expanded their activities within the UK SME sector. This growth has been partly driven by traditional bank balance sheets becoming more selective due to the capital requirements under Basel III. Soho Square’s distinct positioning, which combines sophisticated institutional debt structuring with hands-on strategic support, allows it to compete effectively with this growing cohort of private credit providers, as well as with the mezzanine arms of larger alternative asset managers. Key markers for observers will be the fund’s final close size once the US institutional commitments are fully factored in, the pace at which capital is deployed into Industrial Strategy sectors outside London, and whether the British Business Bank chooses to exercise its co-investment rights on early transactions.
